[0032] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0033] This utility model discloses a suspended steel structure skylight, which can solve the technical problem that the existing technology is prone to failure in rainy or snowy weather, thereby ensuring that the skylight has a longer service life and effectively improving the durability and safety of the skylight.

[0034] The technical solution of this application will be described in detail below through specific embodiments:

[0035] See Figure 1 and Figure 2 According to a first aspect of this application, a suspended steel structure skylight is provided, which includes a mounting frame 100, a window body 200, and a cleaning device 300. The window body 200 is rotatably connected to the mounting frame 100 via a first connecting shaft 110, which is arranged along the width direction of the mounting frame 100. The cleaning device 300 includes a second connecting shaft 301, a third connecting shaft 308, and a cleaning structure. Both the second connecting shaft 301 and the third connecting shaft 308 are rotatably connected to the window body 200. The second connecting shaft 301 is arranged along the length direction of the window body 200, and the third connecting shaft 308 is arranged along the height direction of the window body 200. The second connecting shaft 301 is driveably connected to the first connecting shaft 110, and the third connecting shaft 308 is driveably connected to the second connecting shaft 301. The cleaning structure is installed at one end of the third connecting shaft 308 that protrudes from the window body 200. When the window 200 rotates relative to the mounting bracket 100, the first connecting shaft 110 drives the second connecting shaft 301 and the third connecting shaft 308 to rotate, and the third connecting shaft 308 drives the cleaning structure to move on the window 200.

[0036] The suspended steel structure skylight disclosed in this embodiment uses a purely mechanical structure to clear snow from the window 200, which can effectively prevent erosion by rain and snow, thereby preventing the cleaning device 300 from malfunctioning in rainy or snowy weather.

[0037] See Figure 1 , Figure 2 and Figure 3 The mounting bracket 100 has a frame structure, with a first connecting shaft 110 at its first end. The first connecting shaft 110 is fixedly connected to the mounting bracket 100, and the first end of the window 200 is rotatably connected to the first connecting shaft 110. When the window 200 rotates relative to the mounting bracket 100, the first connecting shaft 110 remains stationary, while the window 200 rotates around the first connecting shaft 110. The middle part of the window 200 is a glass body 210 to facilitate light transmission.

[0038] In this embodiment, with Figure 1 The direction from the lower left corner to the upper right corner is the length direction of the mounting bracket 100, the direction from the upper left corner to the lower right corner is the width direction of the mounting bracket 100, and the vertical direction is the height direction of the mounting bracket 100.

[0039] In one embodiment, a sealing ring 120 is also provided between the window 200 and the mounting bracket 100. When the window 200 is closed, the window 200 squeezes the sealing ring 120 to achieve a sealing effect, thereby preventing cold air or dust from the outside from blowing into the room.

[0040] See Figure 1 and Figure 3 In one embodiment, the cleaning device 300 further includes a first bevel gear 302, a second bevel gear 303, and a third bevel gear 309. The first bevel gear 302 is disposed on the first connecting shaft 110, the second bevel gear 303 is disposed at both ends of the second connecting shaft 301, and the third bevel gear 309 is disposed at the end of the third connecting shaft 308 opposite to the cleaning structure. The second bevel gear 303 on the second connecting shaft 301 near the first connecting shaft 110 meshes with the first bevel gear 302, and the second bevel gear 303 on the second connecting shaft 301 near the third connecting shaft 308 meshes with the third bevel gear 309.

[0041] Of course, the use of bevel gears for transmission between the first connecting shaft 110, the second connecting shaft 301, and the third connecting shaft 308 is only one implementation method in this embodiment. In other implementation methods, other transmission methods can also be used between the first connecting shaft 110, the second connecting shaft 301, and the third connecting shaft 308.

[0042] See Figure 3 and Figure 4 In one embodiment, a first fixed frame 220 and a second fixed frame 230 are provided on the window 200. The first fixed frame 220 is located between the second fixed frame 230 and the first connecting shaft 110. The second connecting shaft 301 is rotatably connected to the first fixed frame 220, and the third connecting shaft 308 is rotatably connected to the second fixed frame 230.

[0043] In one embodiment, the cleaning structure includes a long rod 310, a sliding rod 304, and a push plate 306. The long rod 310 is connected to a third connecting shaft 308, the sliding rod 304 is slidably connected to the long rod 310, and the push plate 306 is connected to the sliding rod 304. When the long rod 310 rotates with the third connecting shaft 308, it can clean snow and debris on the window 200, thereby ensuring the cleanliness of the window 200.

[0044] In one embodiment, the end of the long rod 310 is provided with an outer ring 311, which is sleeved on the third connecting shaft 308 to form a connection with the third connecting shaft 308, so that the third connecting shaft 308 can drive the outer ring 311 to rotate synchronously when it rotates. The outer ring 311 and the third connecting shaft 308 can be fixedly connected by means of key connection or spline connection, etc.

[0045] In one embodiment, the cleaning structure further includes a fixed rod 315, an abutment block 314, and a triangular block 312. The triangular block 312 is connected to a slide bar 304 and is capable of moving synchronously with the slide bar 304 relative to the long rod 310. The fixed rod 315 is connected to the window 200, and the abutment block 314 is connected to the fixed rod 315 and is located on the movement path of the triangular block 312. When the triangular block 312 abuts against the abutment block 314, the abutment block 314 pushes the triangular block 312 and the slide bar 304 in a direction away from the third connecting axis 308.

[0046] The fixing rod 315 can be installed on the second fixing frame 230. The fixing rod 315 is arranged parallel to the third connecting shaft 308, and the fixing rod 315 and the third connecting shaft 308 are spaced apart to avoid affecting the rotation of the third connecting shaft 308. The abutment block 314 is located on the top of the third connecting shaft 308, and the abutment block 314 is spaced apart from the third connecting shaft 308.

[0047] In one embodiment, a sliding rod 313 is provided at the end of the sliding rod 304. The sliding rod 313 is arranged parallel to the third connecting shaft 308. The sliding rod 313 is installed in the groove of the long rod 310. A triangular block 312 is installed on the top of the sliding rod 313, and the triangular block 312 is spaced apart from the long rod 310.

[0048] In one embodiment, the cleaning structure further includes a first elastic element 305. The two ends of the first elastic element 305 act on the push plate 306 and the sliding rod 313, respectively, and the first elastic element 305 drives the sliding rod 313 to move toward the third connecting shaft 308. When the triangular block 312 abuts against the contact block 314, the contact block 314 pushes the sliding rod 304 and the push plate 306 to move away from the third connecting shaft 308. When the protruding portion of the triangular block 312 separates from the contact block 314, the first elastic element 305 pushes the sliding rod 304 and the triangular block 312 back to their initial position, so that when the triangular block 312 and the contact block 314 contact again, the sliding rod 304 and the push plate 306 can move along the long rod 310 again.

[0049] In one embodiment, the push plate 306 is further provided with a curved panel 307, which is located at the end of the push plate 306 away from the third connecting shaft 308 and is curved inward. The combination of the straight push plate 306 and the curved panel 307 can better clean up snow and other debris on the window 200, while the cleaning device 300 is smaller in size.

[0050] In one embodiment, cleaning devices 300 are respectively provided at both ends of the first connecting shaft 110, which can clean the window 200 from both sides when the window 200 is pushed, thereby improving cleaning efficiency and cleaning effect.

[0051] The specific working method of the cleaning device 300 disclosed in this application is as follows:

[0052] Initially, the window 200 closes and compresses the sealing ring 120 to form a seal. When the window 200 is pushed to rotate relative to the mounting bracket 100, the first bevel gear 302 and the second bevel gear 303 rotate relative to each other. Since the first connecting shaft 110 is fixed, the second connecting shaft 301 rotates, thereby driving the third bevel gear 309 to rotate, and driving the third connecting shaft 308 to rotate. When the third connecting shaft 308 rotates, it drives the long rod 310 to rotate. On the one hand, the rotation of the long rod 310 will drive the push plate 306 and the curved panel 307 to rotate synchronously. On the other hand, by utilizing the cooperation of the triangular block 312, the abutment block 314, and the first elastic element 305, the push plate 306 and the curved panel 307 will also reciprocate in the first direction, thereby further improving cleaning efficiency.

[0053] See Figure 1 , Figure 2 and Figure 5 In one embodiment, the suspended steel structure skylight further includes a protective device 400, which comprises a protective plate 401. The protective plate 401 is slidably engaged with the window frame 200, allowing the protective plate 401 to expose or obscure the window frame 200. The protective device 400 is used to protect the window frame 200 from severe physical impacts under extreme weather conditions, such as hail or strong winds. Through its robust structure and tight fit with the window frame 200, the protective device 400 effectively blocks direct impacts from hard objects such as hail, thereby significantly reducing the risk of damage to the window frame 200.

[0054] As an important component of a building, the lifespan of the window 200 directly affects the overall maintenance cost and aesthetics of the building. The protective device 400 helps maintain the integrity and functionality of the window 200 by reducing external impacts on it, thereby extending its lifespan.

[0055] In one embodiment, the protective device 400 further includes an outer frame 402, a lead screw 403, and a sliding frame 404. The outer frame 402 is mounted on the window 200, and the outer frame 402 and the first connecting shaft 110 are located on opposite sides of the window 200, i.e., the outer frame 402 is located at the second end of the window 200 and on the side of the window 200 facing away from the mounting bracket 100. The lead screw 403 is rotatably connected to the outer frame 402, and the lead screw 403 is arranged along the width direction of the mounting frame, i.e., the lead screw 403 is parallel to the first connecting shaft 110. The sliding frame 404 is slidably connected to the outer frame 402, and the outer frame 402 and the lead screw 403 are threadedly engaged. A protective plate 401 is mounted on the sliding frame 404, and rotating the lead screw 403 drives the protective plate 401 to expose or cover the window 200.

[0056] By rotating the lead screw 403, the sliding frame 404 and the protective plate 401 mounted on it can be easily moved, thereby revealing or obscuring the window 200. This operation is simple, quick, and easy to master. The protective plate 401, through the tight fit between the sliding frame 404 and the outer frame 402, can provide a stable protective effect when needed. Even in extreme weather conditions, such as hail or strong winds, the protective device 400 can effectively protect the window 200 from damage. The various components of the protective device 400 are rationally designed and easy to disassemble and install. Cleaning, maintenance, or replacement can be easily performed, reducing maintenance costs and time.

[0057] In one embodiment, a fixing plate 405 is provided inside the outer frame 402, the middle part of the lead screw 403 is rotatably engaged with the fixing plate 405, and the end of the lead screw 403 is rotatably engaged with the side wall of the outer frame 402. By providing the fixing plate 405, the stability of the rotation of the lead screw 403 can be increased.

[0058] By setting the fixed plate 405, the lead screw 403 receives additional support during rotation, thereby significantly enhancing its rotational stability. This helps prevent the lead screw 403 from shifting or being damaged due to uneven force or vibration.

[0059] In one embodiment, two sliding frames 404 are provided, each mounted on one end of a lead screw 403. The threads on the two sliding frames 404 have opposite directions so that when the lead screw 403 rotates, it can cause the two sliding frames 404 to move closer or further apart. Correspondingly, a protective plate 401 is mounted on each sliding frame 404. When the two sliding frames 404 are close together, the two protective plates 401 completely cover the window 200 to provide protection; when the two sliding frames 404 are far apart, the window 200 is exposed.

[0060] By rotating the lead screw 403, the movement of the two sliding frames 404 and their carried protective plates 401 towards or away from each other can be easily controlled. This operation method is not only simple and quick, but also allows for rapid adjustment of the position of the protective plates 401 as needed to meet different usage requirements.

[0061] In one embodiment, the protective device 400 further includes a torsion block 406. The torsion block 406 is rotatably connected to the outer frame 402 and is perpendicularly arranged to the lead screw 403. A fourth bevel gear 407 is provided on the torsion block 406, and a fifth bevel gear 408 is provided on the lead screw 403, with the fifth bevel gear 408 meshing with the fourth bevel gear 407. A rotating column 409 is provided on the torsion block 406, with the fourth bevel gear 407 located at the end of the rotating column 409 opposite to the torsion block 406.

[0062] Rotating the torsion block 406 can drive the lead screw 403 to rotate, thereby causing the two protective plates 401 to move closer to or further away from each other.

[0063] In one embodiment, the protective device 400 further includes a slider 410, a connecting rod 411, and a hinge block 412. The protective plate 401 is rotatably connected to the top of the sliding frame 404, and the rotation direction of the protective plate 401 is parallel to the second connecting shaft 301. The slider 410 is slidably connected to the bottom of the sliding frame 404, the hinge block 412 is rotatably connected to the end of the protective plate 401 opposite to the sliding frame 404, and the two ends of the connecting rod 411 are rotatably connected to the slider 410 and the hinge block 412, respectively.

[0064] In one embodiment, a guide frame 413 is provided on the sliding frame 404, the slider 410 is located inside the guide frame 413, and the slider 410 can slide within the guide frame 413 along the width direction of the mounting bracket 100.

[0065] In one embodiment, the protective device 400 further includes a second elastic member 414. The two ends of the second elastic member 414 act on the sliding frame 404 and the slider 410 respectively, and the second elastic member 414 is used to drive the slider 410 to move toward the end of the protective plate 401 away from the sliding frame 404.

[0066] When the protective plate 401 comes into contact with falling hail or other debris, it rotates downwards. This rotation causes the hinge block 412 to rotate downwards, which in turn causes the connecting rod 411 to rotate downwards. The connecting rod 411 then causes the connecting block on the inner wall of the sliding frame to slide. The elasticity of the connecting block, in conjunction with the second elastic element 414, buffers the impact of the hail, effectively absorbing and dispersing the impact force. This protects the glass structure from damage and reduces potential damage, ensuring the safety and integrity of the skylight under adverse weather conditions.

[0067] Through the above embodiments, this application has the following beneficial effects or advantages: The suspended steel structure skylight disclosed in this application uses a purely mechanical structure to clean snow accumulation on the window 200, which can effectively avoid erosion from rain and snow, thereby preventing the cleaning device 300 from malfunctioning in rainy or snowy weather. Through the cooperation of the triangular block 312 and the abutment block 314, the push plate 306 and the curved panel 307 have the ability to reciprocate, significantly improving cleaning efficiency. This not only increases the cleaning area but also more effectively removes stubborn impurities from the surface of the glass body, further improving the cleanliness of the push plate 306. By setting up the protective device 400, effective protection can be provided for the window 200 under extreme weather conditions. The rotating protective plate 401 and related structures such as the slider 410 and connecting rod 411 can effectively form a buffer, thereby reducing the impact force of objects such as hail.
